PRODUCT OF THE WEEK: Vicor SOSA Power Supply
Sponsored StoryMarch 24, 2025
This week’s product, Vicor’s SOSA Power Supply, is aligned with the Open Group’s Sensor Open Systems Architecture, or SOSA, Technical Standard and designed for 3U OpenVPX systems that are aligned to the SOSA approach. The commercial off-the-shelf (COTS) device is targeted at avionics, shipboard applications, and other defense applications.
The module leverages Vicor proprietary technology to enable high efficiency and power density for this rugged, conduction-cooled power supply.
As many as four power supplies can be paralleled to increase output power capability of +12V main and +3.3V auxiliary outputs with proprietary wireless current sharing. The need for conventional current‑share pins is eliminated and current share accuracy is ±2A.
